半导体芯闻· 2025-08-07 10:33
Core Viewpoint - Morgan Stanley reports that Nvidia is exploring a revolutionary chip packaging technology called CoWoP (Chip-on-Wafer-on-PCB), which is expected to replace the existing CoWoS packaging solution [2][3]. Group 1: CoWoP Technology Analysis - CoWoP utilizes advanced high-density PCB technology, eliminating the ABF substrate layer found in CoWoS packaging, and directly connecting the intermediary layer to the PCB [4]. - The potential advantages of CoWoP include simplified system structure, improved thermal management, lower power consumption, reduced substrate costs, and potential reduction in backend testing steps [10]. Group 2: Supply Chain Impact - The introduction of CoWoP is seen as negative news for ABF substrate manufacturers, as the added value of substrates may significantly decrease or disappear [8]. - Conversely, PCB manufacturers are presented with significant opportunities, particularly those with advanced mSAP capabilities and deep knowledge of substrate/packaging processes [8]. Group 3: Commercialization Challenges - Morgan Stanley analysts believe that the commercialization probability of CoWoP in the medium term is low due to multiple technical challenges [3][9]. - Current PCB technologies, even with mSAP, can only achieve line/space widths of 20-30 microns, which is still far from the desired performance levels [11]. Group 4: Nvidia's Innovation Leadership - Regardless of the success of CoWoP, Nvidia continues to lead innovations in data center AI infrastructure through a system-level approach [12]. - Nvidia's ongoing innovation capabilities are expected to maintain its leading position in the GPU sector and dominate competition with ASICs in the coming years [12].
